common way to use form validation

i do see what you're doing, but i don't really know why. what for is that your best practice?
i personally don't like to put a lot of data in the session. I do use a db-table with temporary data using

Code:

$this->input->ip_address()   and   $this->session->userdata('session_id');

to organize them.
